Job Title: Specialist Control Systems Analysis Engineer (Systems Engineer)

Job Code: 38007

Job Location: Huntsville AL

Job Schedule: 9/80: Employees work 9 out of every 14 days totaling 80 hours worked and have every other Friday off

Job Description:

The Models Simulations and Controls department is seeking an engineer for a full-time position to support advanced missile propulsion development programs.

This position focuses on the requirements modeling analysis simulation and control development of controllable solid rocket motor and throttling propulsion systems for current and future aerospace and defense applications. The role is ideal for engineers with experience in control systems guidance/navigation/control (GNC) flight dynamics actuation systems dynamic modeling and/or propulsion system analysis.

We are seeking candidates with a strong foundation in either aerospace control theory/GNC or propulsion system analysis. Because this is a specialized application area the selected candidate will receive domain-specific training and will work closely with a multidisciplinary team of propulsion avionics software and test engineers.

You will work on a highly specialized and technically challenging class of aerospace control problems involving controllable solid propulsion systems. This role offers the opportunity to apply core controls and GNC skills in a unique high-impact area while partnering with a collaborative team across propulsion avionics software and systems engineering.

Essential Functions:

  • Perform control algorithm design analysis and evaluation for solid rocket motor throttling and related actuation systems.
  • Support modeling and analysis of propulsion system dynamics including steady-state and transient performance.
  • Develop and apply dynamic models and simulations for aerospace control systems and controllable propulsion systems.
  • Develop and use engineering tools in MATLAB/Simulink and C/C for simulation analysis and control development.
  • Support development of system subsystem and component-level requirements.
  • Collaborate with avionics software systems propulsion and test engineering teams to support integrated system development.
  • Support ground test and system test activities.
  • Prepare and present technical work products for internal reviews customer briefings and program milestones.
  • Support multiple ongoing and future development efforts in a cutting-edge engineering environment.
  • Travel: 10% Offsite testing as required.
  • Ability to obtain a US Secret Security Clearance.

Qualifications:

  • Bachelors Degree and minimum 4 years of prior technical experience in controls GNC propulsion analysis simulation or related aerospace systems work experience. Graduate Degree and a minimum of 6 years of prior technical experience in controls GNC propulsion analysis simulation or related aerospace systems work lieu of a degree a minimum of 8 years of prior technical experience in controls GNC propulsion analysis simulation or related aerospace systems work experience.

Preferred Additional Skills:

  • Bachelors degree in Aerospace Electrical Mechanical Systems Engineering or related technical discipline is preferred.
  • Active U.S Secret Security Clearance is preferred.
  • Experience in one or more of the following areas:

    control systems analysis or control theory

      • guidance navigation and control (GNC)
      • dynamic system modeling and simulation
      • actuator/system response modeling
      • vehicle dynamics flight dynamics or propulsion system analysis
  • Experience working in a classified environment.
  • Experience with MATLAB/Simulink and at least one programming language such as C C or Python.
  • Experience with aerospace controls GN&C missile/munition control systems flight simulation or vehicle performance analysis.

  • Experience with propulsion systems especially propulsion controls throttling systems integrated propulsion/vehicle modeling or propulsion test support.

  • Experience with high-fidelity simulation time-domain analysis and control system performance assessment.

  • Familiarity with 6-DoF or reduced-order dynamic simulations actuator models or hardware/software integration.

  • Experience supporting test planning test execution hardware-in-the-loop/software-in-the-loop activities or post-test data analysis.

  • Experience developing or evaluating embedded or real-time control-related software.

  • Test and evaluation of dynamic aerospace systems
